Gastrointestinal cancer includes cancers of the esophagus, stomach, small bowel, pancreas, bile duct, and liver. Several kinds of cancer can occur in the stomach. The most common type is called adenocarcinoma, which starts from one of the common cell types found in the lining of the stomach.Adenocarcinoma of the stomach is a common cancer of the digestive tract. Symptoms
The symptoms may vary from abdominal fullness or pain, which may occur after even a small meal to loss of appetite. There can be dark stools, difficulty in swallowing, which becomes worse over time, excessive belching, and general decline in health, nausea, vomiting, which may contain blood, weakness or fatigue and weight loss.Causes
You are more likely to get gastric cancer if you have a family history of gastric cancer. If you have inflammation and swelling of the stomach for a long time (chronic atrophic gastritis) and have pernicious anemia. Detection
Diagnosis is often delayed because symptoms may not occur in the early stages of the disease.
Many a times patients may self-treat symptoms that gastric cancer has in common with other, less serious gastrointestinal disorders for example, bloating, gas, heartburn, and a sense of fullness.Diagnostic Tests
Some tests can help diagnose gastric cancer such as -Complete blood count (CBC) to check for anemia; Esophagogastroduodenoscopy (EGD) with biopsy to examine the stomach tissue and stool test to check for blood in the stools.Word of advice
Radiation therapy and chemotherapy may be useful. For many patients, chemotherapy and radiation therapy after surgery may improve the chance of a cure.For patients who cannot have surgery, chemotherapy or radiation can improve symptoms and may prolong survival.
